Red leverages seamless coordination among the Rook, Cannon, Knight, and advanced Pawn to paralyze Black's Palace. By sealing the King's escape routes with the advanced Pawn, Red executes a decisive tactical assault before Black can mount a counterplay.
In this position, Red's combined attack force of Rook, Cannon, Knight, and Pawn creates an overwhelming assault force targeted directly at Black's Nine Palaces. The Red Pawn wedged deeply on the 7th rank acts as an indispensable anchor, severely restricting the Black King's movement while providing tactical pivot points for the Knight. Black's defense suffers from disorganized Palace guards, leaving the King vulnerable to long-range Cannon threats and file-controlling Rook pins. The strategic key lesson highlights multi-piece synergy: establishing a deep pawn wedge while maintaining the initiative allows heavy back-line pieces to weave an inescapable checkmate net.
